I am planning my honeymoon for March, but I have no idea where to go. The Caribbean or South America?

If you want to maximize your destinations i would look into caribbean and south american cruises, i’ve been on royal caribbean cruise line and its great. Im sure you can find a cruise that allows you to visit south america (however argentina is too far away)and the islands of the caribbean
try the royal caribbean site for ideas,

Barbados is a perfect place for honeymoons and other reasons in the Caribbean.

You can check Little Arches, the boutique hotel that won an award from TripAdvisor this year.

There’s also some Almond resorts to look into as well to see which suits you better.

Try a combination. First you go to Argentina. In march it is autumn over there. So you have to go early March. on your way back home you make a stop in the Caribbean to warm up for the summer.

A nice island to visit with a different outlook is Curacao.

Have a nice journey and do not forget to marry under conditions. You are not here to make your fiancee unhappy.

I would definitely recommend the Caribbean for your honeymoon. The rates are really low right now for the place I stayed at, Harbour Heights. The places are really nice and the resort is located on the world famous Seven Mile Beach. There are lots of fun things to do as well as just relaxing on the beach.
